Meteorite

Mars rover Perseverance helped scientists study layered rocks like these in Jezero Crater on the Martian surface. Scientists initially thought they were sedimentary rocks, but further examination showed them to be igneous rocks – solidified lava. These rocks show evidence of interaction with water, but on a limited basis. They date back nearly 4 billion years, giving scientists a window into what conditions on the early planets were like.

Mars was covered by 300 meter deep oceans
